Monitoring model determination method and device

Abstract

The invention provides a monitoring model determination method and device. The method comprises the steps of creating a three-dimensional building model and an initialized monitoring model in a to-be-monitored building construction range, wherein the monitoring model comprises multiple sets of monitoring equipment and monitoring parameters of the monitoring equipment; simulating deployment of themonitoring equipment in the to-be-monitored building construction range based on the three-dimensional building model; determining a monitoring range of a single set of monitoring equipment accordingto the monitoring parameters of the monitoring equipment; determining a blind area range of the monitoring model in the to-be-monitored building construction range according to the monitoring range ofthe single set of monitoring equipment; determining whether the monitoring of the building construction area reaches an expected effect or not according to the blind area range; and if the expected effect is not achieved, adjusting at least one of the number of sets of monitoring equipment simulated and deployed in the monitoring model, the deployment positions of the monitoring equipment and themonitoring parameters of the single set of monitoring equipment.

Description

Technical field [0001] The present invention relates to the field of monitoring technology, in particular to a method and device for determining a monitoring model. Background technique [0002] The video surveillance system is an important part of the security system, which can effectively monitor the flow of people and human behavior within a certain range, and help to detect and deal with some hidden safety hazards within the monitoring range. Video surveillance systems are widely used, especially in crowded public places such as railway stations, subway stations, bus stations, airports, schools, etc. The establishment and improvement of video surveillance systems can greatly improve the safety of surveillance places. [0003] At present, the design of the monitoring system can only place the camera on the two-dimensional construction drawing according to the relevant design specifications and design experience. The construction unit constructs according to the drawing, and the ...

Problems solved by technology

[0003] At present, the design of the monitoring system can only be arranged on the two-dimensional construction drawing according to the relevant design specifications and design experience. In use, it is easy to have blind spots in the monitoring space due to the unreasonable installation position and quantity of the cameras, or the problem that the definition of the monitoring target is not enough
